It took Carter two years to perfect the recipe, which consists of buckwheat that she sprouts herself, blended linseed or flaxseed with coconut oil and sea salt.
"The hardest part was figuring out quantities and how long to bake it for to make sure it would stick together when you toast it," explains Carter, who began making her own bread as a hobby while working at Sydney's famed Bourke St Bakery, before moving back to New Zealand a little over a year ago.
One "really filling and dense" loaf goes for $15.50, and Carter says she's struggling to keep up with demand.
"Sprouted bread is lower in starch, and has higher proportions of other nutrients, like protein, vitamins and minerals. Plus it's great for people with allergies and lasts at least 10 days in the fridge."
She has just finished making her own starter for a new Were Bros sprouted sourdough bread using pumpkin and sunflower seeds. "I haven't seen a dense sourdough before. I like using ingredients no one else is using, and putting them together in a way no one else is," she says.
Meanwhile, Harriet's Handknits, which the duo expect to launch under the Were Bros name and on its website this spring, will include all-natural cotton jumpers, French-style underwear sets and even swimsuits ("They just take a little longer to dry than Lycra togs") that Carter will test herself on a trip to Greece in June.
After finding vintage patterns that she loves, Harriet, who also works as a photographer, sets about "modernising" them before having the designs hand-knitted by two 80-something-year-old Auckland women, who are happy to share their long-forgotten family secrets with the twins.
"That's what's cool about being in New Zealand. There is less competition and more people willing to help. So, if you have an idea and are able to do that one idea really well, there is more space for growth - and there is actually a chance you can do well from it," says Carter, who, when she gets back from working on an organic farm in Greece this August, will complete a permaculture course in order to expand Were Bros into other sustainable areas.
"I'm becoming more interested in the growing of food, and a way of living sustainably and self-sufficiently, where you have a set of systems in place to eliminate waste.
"Nowadays, people are becoming more aware of where their food comes from. They go out of their way to find natural produce and products, and that's what Harry and I want to provide, in all areas of life."
Despite not having a university degree ("I get bored easily, and I can't sit still in a classroom," she admits), Carter has a hungry appetite to learn.
"I want to know all the practical stuff; how to live."
Their grandfather's kiwifruit farm in Hikuai will be Were Bros' first large-scale challenge. "There's a little hut there where the kiwifruit workers used to sleep. I want to fix it up so it's liveable for weekends, and I want to grow vegetables, plant fruit trees, farm animals that I'd eat, make cheese and, hopefully, have people up there who are keen to help out."
